Blank outlined thumbnails

What version of iPhoto? What version of the OS?

I have a similar issue. I have a new iMac 21.5" with iPhoto '11. I moved over 5,000 photos from my old computer (iPhoto '09) by dragging the iPhoto library onto an external hard drive, then dropping it into my new Pictures folder. I then also loaded photos directly from my camera into iPhoto '11.

iPhoto has crashed at least 4 times in the past day, and as I scroll through the photo thumbnails, they disappear as I scroll. If I try to double click on anything newer than about March 2012 (when, coincidentally, I got a new lens), I can see the thumbnails below, but get the triangle with the exclamation. The photos I loaded from my camera are gone.

Also, anything I try to do in iPhoto on my new, lightning-fast computer responds with a beach ball.

Should I start over? Is there a better way to bring the photos over?

Thanks!

As a Test:

Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'

Import a few pics into this new, blank library. Is the Problem repeated there?

So far, so good. Now I'm trying to import the photos from my camera.

If this works, should I be able to drop in my old iPhoto library from my external drive?

Also - thanks for the quick reply. Happy New Year!

This was a test:

It tells us that the app is sound and the problem specific to that Library. Assuming i worked normally on the old machine I would try copy it over again.
